TDK Introduces Single-Phase EMI Filters Designed for Power Supply and Industrial Electronic Applications
TDK Corporation has unveiled a significant addition to their product line with the B84742A*R725 series - a state-of-the-art collection of single-phase EMC filters suitable for AC and DC uses. These filters are engineered for up to 250 V in voltage and have rated currents that vary from 6 A to 30 A.
Responding to the increasing preference for DC solutions in industrial and construction markets, TDK's new B84742A*R725 series presents itself as a compact option. With dimensions of only 97 x 60 x 34.5 mm (L x W x H) and with a maximum weight of 310 grams, these filters are not only compact but also user-friendly. Designed for easy mounting onto a TH35 DIN rail, installation is convenient and rapid. The M4 screw-fastened conductors are thoughtfully designed with protective measures to prevent accidental contact.
The B84742A*R725 series is recognized for its exceptional suppression capabilities, offering up to 40 dB in common mode and over 80 dB in differential mode noise reduction across a 70 kHz to 10 MHz frequency spectrum. Additionally, these filters exhibit low leakage currents under 2 mA, reducing the risk of undesired RCD trips and enhancing overall safety.
These filters are built to exceed industry benchmarks, with all models receiving UL certification and rated for temperatures as high as 55 °C, ensuring consistent operation across various environmental conditions.
Furthermore, the resilience of these filters is displayed in their capacity to manage occasional surges in current, tolerating up to 150% of rated current for three minutes every hour and an extraordinary 250% for 30 seconds every hour. This is especially beneficial for drive applications, where it enables smooth motor startups. The versatile B84742A*R725 series is appropriate for an array of applications, including power supplies, industrial electronics, and ICT.
TDK's B84742A*R725 series stands out as a flexible and dependable filtration solution, meeting the progressively complex demands of the industrial landscape while affirming TDK’s dedication to providing the forefront of technological advancements.
